The TriAero > programs are unstructured versions of the standard linearized > aerodynamic codes used in conceptual/preliminary design. There are four > modules bundled under TriAero - Trisurf, Triwave, Trifrict and Trishabp. > > TriSurf -- A program to create an unstructured wetted surface from a > wire-frame (*.hrm) file. The Boolean operations aren't 100% robust, but > it does pretty well. > > TriWave -- An unstructured Harris wave drag code. Unlike AWAVE (Harris > Wave drag program), it properly and easily represents the shape & volume > of an aircraft. > > TriFrict -- An unstructured skin friction drag code. Local wetted-area > & Reynolds number for each major component are calculated & the skin > friction drag is summed. Very simple, but slightly more complex > versions may be easily implemented. > > TriSHABP -- A clever unstructured input file preparer for S/HABP, the > Gentry Hypersonic Impact program. S/HABP is by nature structured, but > it contains a redundant hierarchy in the input structure. This > redundancy is used to generate unstructured input files. This program > is very immature and may not deserve the 1.0 label, however it does > serve as a proof of concept for unstructured S/HABP input file generation. > > Please refer to the webpage, http://triaero.sourceforge.net for further > details. > > These modules have been written as a part of my thesis work, where I > have created many geometries and tried to optimize their shape using > genetic algorithms. I have many aircraft geometries which failed during > the GTS Boolean operations :). As GTS improves, so will TriAero. If any > of the GTS developers need some of these failed geometries for debugging > purposes, I would be glad to share them with you. > > I welcome all of you to look at the TriAero project and use it according > to your need. All suggestions for improvements are welcome. > > Once again welcome to the TriAero Project. > > Regards, > Sriram >
